Notes. Although
it differs little from A. thompsonae and A. parviflora in its
measurements, it grows sympatrically with these species and the specimens from
a mixed collection can be readily separated on inflorescence characters. Agrostis
differs readily from A. parviflora in the larger
inflorescence with more flexuose branches and longer pedicels.
